Description
Technical field
The present invention relates to a kind of carrier aggregation technology, relate in particular to a kind of 3G network and 4G network carriers polymerization and system.
Background technology
At Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division Multiple Access) in the network, universal land radio access web (UTRAN, Universal Terrestrial Radio Access Network) comprises radio network controller (RNC, Radio Network Controller) and base station (NodeB) two kinds of basic network elements, be commonly called as the third generation (3G, 3rd Generation) communication network.At Long Term Evolution (LTE, Long Time Evolution) in the network, evolved universal land radio access web (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) comprises that this a kind of Basic Net of evolved base station (eNB) is first, be commonly called as the 4th generation (4G, 4th Generation) communication network.
Development along with the WCDMA network, high-speed downstream receiver grouping access (HSDPA, High Speed Downlink Packet Access), high speed uplink sends link packet access (HSUPA, High Speed Uplink Packet Access), two carrier wave high speed downlink packet access (DC-HSDPA, Dual Carrier-High Speed Downlink Packet Access), the two carrier wave high speed downlink packet access of two-band (DB-DC-HSDPA, Dual band-Dual Carrier-High Speed Downlink Packet Access), two carrier wave high speed uplink packet access (DC-HSUPA, Dual Carrier-High Speed Downlink Packet Access), four carrier wave high speed downlink packet access (4C-HSDPA, Four Carrier-High Speed Downlink Packet Access), eight carrier wave high speed downlink packet access (8C-HSDPA, Eight Carrier-High Speed Downlink Packet Access) the intrasystem multi-carrier polymerizing technology of these 3G is introduced into successively, so that the up-downgoing data transmission rate of subscriber equipment (UE, User Equipment) improves constantly.Multi-transceiver technology for above-mentioned different dimensions, take down direction as example, an important essential characteristic is: UE must be equipped with the relevant receive data processing chain (3G-Receiver Chain) of many 3G, simultaneously the reception ﹠ disposal 3G data block of sending from several carrier wave up-downgoings of same sector, same base station (sector).The WCDMA system that evolves to today is called again HSPA+ (High Speed Packet Access+) system.
Development along with the LTE network, the technology of similar WCDMA multi-carrier polymerizing concept (CA, Carrier Aggregation) also produces gradually, take down direction as example, by up till now, maximum can be carried out polymerization to the carrier wave that 5 downlink bandwidths are 20MHz in the LTE system.The important essential characteristic of carrier aggregation is: UE must be equipped with the relevant receive data processing chain (4G-Receiver Chain) of many 4G, simultaneously the reception ﹠ disposal 4G data block of sending from several carrier wave up-downgoings of same sector, same base station.
The HSPA+ network must have a very long time in the long-term flow process of LTE network evolution, two kinds of systems exist and collaborative work simultaneously, shared from or towards the task of the transfer of data of core net one side.Such as, there are two carrier frequency point resource F1, F2 in certain operator, F1 is distributed to the HSPA+ network operation use, and uses and F2 is distributed to the LTE network operation.Only have the UE of 3G function to work at F1, only have the UE of 4G function to work at F2, possess simultaneously the terminal of 3G, 4G function, at the same time, can only work at F1 or F2, can not work at F1 and F2 simultaneously.For the receiving ability that takes full advantage of this class UE with improve descending peak rate, industry has proposed the 7th generation (7G, the 7th Generation) communication technology (3G+4G) and has claimed again to stride HSPA+, LTE system carrier aggregation technology.
Fig. 1 is the composition structural representation of 7G network, and as shown in Figure 1, the eNB of LTE connects master control anchor point and the data distribution control point of (RRC, Radio Resource Connection) in the 7G network architecture as the UE Radio Resource.Physical Downlink Control Channel (the PDCCH of UE on eNB work carrier wave, Physical Downlink Control Channel) dispatching command in (distributes such as resource, HARQ (Hybrid Automatic Repeat ReqUEst) operates relevant information) control is down, (PDSCH, Physical Downlink Shared Channel) receives a part of user data from Physical Downlink Shared Channel.Simultaneously, High-Speed Shared Control Channel (the HS-SCCH of UE on NodeB work carrier wave, High Speed Shared Control channel) dispatching command control is lower, from the upper another part user data that receives of high speed descending sharing channel (HS-DSCH, High Speed-Downlink Shared Channel).Anchor point eNB is responsible for the upper-layer protocol packet that eNB produces is distributed, and according to certain mode, determines which part sends from the air interface of LTE, and which part sends from the air interface of HSPA+.Be assigned to that a part of protocol data bag of NodeB, need to be by new interface transmission between eNB and the NodeB, sent according to the mode of self agreement characteristic and HSPA+ air interface by NodeB.
At up direction, UE will send physical uplink control channel (PUCCH with the work up frequency of descending frequency pairing of eNB at least, Physical Uplink Control Channel), carrying is such as HARQ operation relevant information (correct confirmation of receipt ACK/NACK) among the PUCCH, dispatch request, receive channel quality indications etc. are with the relevant necessary information of feedback LTE down high-speed data transmission.And whether UE will send High-Speed Dedicated Physical Control Channel (HS-DPCCH with the work up frequency of descending frequency pairing of NodeB, High Speed-Dedicated Physical Control channel), with the relevant necessary information of feedback HSPA+ down high-speed data transmission, prior art not yet relates to.Usually in order to reduce the uplink transmission power of UE, and reduce uplink interference, tend to UE and only eat dishes without rice or wine to carry out the single system uplink feedback at HSPA+, but not cross-system feeds back simultaneously.The intrasystem carrier aggregation technology of 7G technology and HSPA+ or LTE is not conflicted, UE might do data receiver at M the carrier wave of HSPA+, simultaneously do data receiver at N carrier wave of LTE system again, the work basic principle is the same, can expand to higher dimension.
The 7G technology can be fully and is utilized neatly 3G, characteristic distributions that 4G system resource is different, realizes cross-system load balancing, switching etc., can also realize to a deeper level the collaborative work of 3G, 4G system.3G, 4G system both can share dissimilar business such as the voice HSPA+ system CS territory of trying one's best away, and the high-speed data service LTE system that tries one's best away also can bear simultaneously identical business such as data business and be assigned to two systems and transmit simultaneously.
